WebThere are two important ways to recognize different types of waves in seismic records: Their velocity. These waves travel at different speeds: P-waves are fastest, then S-waves, then Love waves, then Rayleigh.Since … Webedge divided by the velocity of a Rayleigh wave in steel. Instead the Rayleigh-wave arrival time (as will be demonstrated later) corresponded to the distance from the PLB position …

Webrecorded Rayleigh waves (specific type of surface wave) generated using either an active and/or passive acoustic source into a 1-D shear-wave velocity profile of the subsurface. If MASW data are acquired at multiple sites along a traverse, the output 1-D shear wave velocity profiles can be used to generate a 2-D velocity image of the subsurface.
Generation from earthquakes Because Rayleigh waves are surface waves, the amplitude of such waves generated by an earthquake generally decreases exponentially with the depth of the hypocenter (focus). However, large earthquakes may generate Rayleigh waves that travel around the Earth several … See more Rayleigh waves are a type of surface acoustic wave that travel along the surface of solids. They can be produced in materials in many ways, such as by a localized impact or by piezo-electric transduction, … See more Rayleigh waves are a type of surface wave that travel near the surface of solids. Rayleigh waves include both longitudinal and transverse motions that decrease exponentially in amplitude as distance from the surface increases. There is a phase difference … See more Rayleigh waves propagating at high ultrasonic frequencies (10–1000 MHz) are used widely in different electronic devices. In addition to Rayleigh waves, some other types of surface … See more • Linear elasticity • Longitudinal wave • Love wave See more Rayleigh waves are widely used for materials characterization, to discover the mechanical and structural properties of the object being tested – like the presence of cracking, and the related shear modulus. This is in common with other types of surface … See more Low frequency (< 20 Hz) Rayleigh waves are inaudible, yet they can be detected by many mammals, birds, insects and spiders.

WebAs the displacements of Rayleigh waves decay exponentially with depth, Rayleigh waves are confined to a depth of 1 − 2 λ R from the surface [51], where λ R is the Rayleigh wavelength. In this study, we only consider Rayleigh waves that propagate in the soil, whose wave lengths satisfy 2 λ R ≤ h . http://masw.com/files/XIA-00-02.PDF
